With the rise in popularity of tripod shooting and hunting, the need to adapt rifles with MLok forends and rails to work with high-end Arca-Swiss ballheads and fixtures arose. Machined to the same exacting tolerances and specifications as Really Right Stuff / RRS, the ANNEX Arca-Swiss to MLok rails have integrated hard-stops at the end of the rails to prevent the rifle from sliding off the ball-head / tripod, integrated threaded holes to install your own stop-points at various locations with the included screws, and are CNC machined from a solid block of aerospace-grade aluminum.
